the obama administration is investigating itself with secret internal probes. now, aren't those by their very nature, inherently suspect and all the more reason why congress needs to conduct an independent investigation? >> i think investigations by both branches are appropriate. i think in the case of the obama administration, it's not only that their investigations have produced accounts so far which are only favor annual to them -- favorable to them, but the selective leaking of information has politicized the central intelligence agency and the pentagon, just a few days before our election. there is another letter out by another group of senators, senators coats and blunt and rubio and others if i recall, that go precisely to that point. are these leaks authorized by the administration, or are these leaks by the agencies themselves? what this shows is i think the administration disarray and simply underlines the importance of congress getting to the bottom of this. >> gregg: katherine herrage obtained a classified cable from the u.s. mission in benghazi les
